STEEL SHEET PILES
2Wide Selection of Shapes and TypesSheet pile is available in a wide range of section modulus per meter of pile wall, ranging from 874 to 21,846 cm/m. This allows selection of the most economical type of sheet pile to meet the design requirements and the intended construction method.
Superb Drivability and WatertightnessThe clearance between the two threaded interlocks is moderate enough to ensure both excellent drivability and reliable watertightness.
Features
(1) Quick construction: Dramatic reduction in the construction period
(2) Reliability for long-term use: Increases the safety factor and reduces the deformation of the wall using robust steel sheet piles
(3) Availability of long pile and deep embedment: Up to 38m in length
(4) Sustainability: Remove and reuse possible(5) Availability of narrow areas
Advantages of steel sheet piles over other methods (masonry, RC walls, etc.)

STEEL SHEET PILESNIPPON STEEL & SUMITOMO METAL
Small-scale excavation
Large-scale excavation
The vertical load in the axial direction like a crane load is applied and the bearing force against the vertical load is expected. Welding can't be carried out near the site.
Example of solution proposed by usWe want to use our land to the utmost. Can you provide a good steel sheet pile?
Do you have any steel sheet pile method that is environmentally friendly?
Do you have a steel sheet pile that can be easily installed?
Can you provide a good method to build a large-scale revetment for reclamation?
We want to minimize deflection for safety when the front of a steel sheet pile is excavated. Can you provide a good steel sheet pile?
Each pile of a wall has a uniform shape and rigidity. Therefore only one type of piling machine is required for installation and the sequential installation in the same direction is possible. This leads to easy installation. (Refer to pages 15 and 16.)
This is a gravitational wall featuring a cylindrical shape assembled with straight web-type sheet piles. Inside is filled with sand. It is excellent in structural stability. A prefabricated sheet p i l e ce l l me thod can provide quick construction. (Refer to pages 17 and 18.)
Unlike a concrete-based temporary earth-retaining wall, the steel sheet pile wall can be repeatedly used and is environmentally friendly. In construction, sludge is not generated, and the disposal of soil is not required. (Refer to pages 13 to 16.)
The moment of inertia is almost twice as large as that of Z-type sheet pile. This leads to reduction of deection and the number of struts. The sheet piles can be re-used multiple times. (Refer to pages 15 and 16.)
The clearance between the threaded interlocks is moderate enough to make it easy to install sheet piles which are installed afterward while pipe piles are installed forward. This clearance can absorb the inaccuracy of the positioning of pipe piles and sheet piles. (Refer to pages 23 and 24.)
This is a gravitational wall in which steel sheet piles are installed in two rows. The tops of the sheet piles are connected by tie rods. And the space between the sheet piles is filled with sand. It is excellent in structural stability. By dividing the construction site into multiple zones and by pairing a group of ships, the construction lead time can be reduced.
The steel sheet pile is a good method to construct a revetment quickly. The special function required to construct the revetment for reclamation is the stability against waves until the completion of reclamation. The structure must be safe even without back reclamation.
Depth of approx. 10 m 15 m
Temporary earth-retaining wall
The interlocks are situated on the outmost side of the section. This makes it unnecessary to consider the reduction of sectional properties which are factored in with U-type sheet piles. This leads to reduction of the number of struts. The sheet piles can be re-used multiple times. (Refer to pages 13 and 14.)

This is our complimentary engineering support to our customer. (Our proposal is for reference of our customer. The responsible judgment is up to the customer.) (Refer to pages 11 and 12.) Various types and sizes of sheet piles are available. The optimum type and size is selected based on the design conditions and the construction method. (874cm3/m to 21,846cm3/m) (Refer to pages 7 and 8.)

In the case of construction of a revetment at a seaside where a week layer exists, the improvement of soil is eliminated by embedding sheet piles into the load-bearing layerunlike a concrete caisson or stone revetment. This is an environmentally friendly method. (Refer to pages 17 and 18.)
Seawall
Steel sheet pile cell
The vertical load in the axial direction like a crane load is not applied. Welding can be carried out near the site.
NS-SP-J pile and the dedicated press-in piler can construct a earth-retaining wall without dead space. This enables the full use of the premises to the boundary limits. (Refer to pages 25 and 26.)

STEEL SHEET PILESNIPPON STEEL & SUMITOMO METAL
Superb drivabilityThe large sectional area of the Hat-type sheet pile realizes superior drivability. High structural reliability
No reduction is required in sectional properties to consider the possible lack of shear force transmission at the interlocks, which is true for U-type steel sheet piles.
Excellent cost-effectivenessThe amount of steel per unit wall can be reduced, resulting in improved total cost.

The sectional properties of Hat-type sheet piles after 1 mm of corrosion loss per side, totaling 2 mm on both sides, are shown in the table below.
Steps to calculate sectional properties after corrosion; Assume the corrosion rate and lifetime of the facility, and
calculate the corrosion loss of the marine side t (mm) and that of the land side t (mm).
Calculate the corrosion loss rate (=t/t).Using the corrosion loss of the marine side t (mm) and the
corrosion loss rate , obtain the reduction ratio of the sectional properties from the following graphs.Calculate the sectional properties after corrosion loss, Z and I, by
multiplying the sectional properties before corrosion loss, Z with I by the reduction ratio .

STEEL SHEET PILESNIPPON STEEL & SUMITOMO METAL
Interlock integrity of sheet pilesWhen a wall using U-type steel sheet piles is subjected to bending due to soil pressure or other horizontal load, a large bending shear force occurs in the interlocks of the sheet piles because these interlocks are located at the center of the wall (neutral axis position).In this case, If the shear force doesnt transmit sufficiently between the adjacent the interlocks slip from each other, and the moment of inertia and section modulus of the wall of the sheet piles are reduced. This can be referred to as "lack of interlock integrity". And the degree of reduction is expressed by reduction factor. In contrast, for a wall using Hat-type steel sheet piles, the reduction of sectional properties is not required because interlocks are located at the most outer edge of the wall, which means that the shear force does not occur in the interlocks. Reduction factors of sectional properties from code to code. An example of the Eurocodes is shown below.
Interlock integrity in Hat-type steel sheet piles
Example of a trial design for temporary retaining walls
Steel-weight comparison between U-type and Hat-type, the sectional properties of which are reduced using by interlock factors
Bending tests for Hat-type steel sheet piles in the form of a wall as well as in the form of a single pile have been conducted. It is confirmed that the design values of the load-displacement relationship are in agreement with the experimental values. This demonstrates that the reduction of sectional properties is not required.
The reduction factor of U-type steel sheet piles is set as 0.45 for the moment of inertia, with 0.6 for the section modulus, in order to compare U-type and Hat-type using the same design conditions. NS-SP-25H (Hat-type) shows design results that are roughly equivalent to those of NS-SP-IV (U-type), and the number of short strut rows and the length of the steel sheet piles are mostly the same. However, the weight of NS-SP-25H (Hat-type) is 66% that of NS-SP-IV (U-type). When using NS-SP-45H (Hat-type), the working space increases during excavation with only one strut row, and the working efciency of concrete structure fabrication is greatly improved, enabling a construction cost reduction for the concrete structure. Although the weight increases compared with NS-SP-25H, NS-SP-45H is still 89% that of NS-SP-IV (U-type), and thus a weight reduction benet can be obtained.
We have conducted performance evaluation for the repeated use of Hat-type steel sheet piles based on the field tests. So far, we have conducted these tests for the cases of different installation methods such as vibratory hammer methods and press-in methods.

Availability of numerous sectional propertiesHat-type and H-shape combined high stiffness steel sheet piles come in combination of Hat-type sheet piles which have four types and H-shape sections which have many types. Eventually they provide more than 200 types of economical properties. (Section modulus per meter of wall : Approx.2,320 to 19,970cm3/m)
Ease of fabricationIt is easy to fabricate Hat-type and H-shape combined high stiffness steel sheet piles by combining Hat-type and H-shape with intermittent llet welding. Welding can be carried out at the site or the nearby yard or shop.
Excellent cost-effectivenessFrom the viewpoint of design for the Hat-type and H-shape combined high stiffness steel sheet pile, Hat-type functions as a continuous wall to sustain soil and water, and H-shape functions as a structural member to bear the bending moment. This makes it possible to use low-cost H-shape up to 50 to 70% of weight as well as avoiding use of expensive connectors to connect a sheet pile and a section.
Ease of InstallationAn ordinary vibratory hammer is directly applicable for driving. The Hat-type and H-shape combined high stiffness steel sheet pile, having higher moment of inertia per pile compared with Z-type and other type piles, is very easy to work with.

Manual for fabrication
Corrosion loss is considered, based on Eurocode 3, Design of steel structures - Part 5: Piling (BS EN 1993-5:2007). Sea-side corrosion loss (t1) is based on the recommended values of the seawater in a temperate climate in the zone of permanent immersion or in the intertidal zone, as in Table 4-2. Land-side corrosion loss (t2) is based on the recommended values of undisturbed natural soils (sand, silt, clay, schist, etc.), as in Table 4-1.
We have conducted performance evaluation for the repeated use of Hat-type and H-shape combined high stiffness steel sheet piles based on the field tests. So far, we have conducted these tests for the cases of different installation methods such as vibratory hammer methods and press-in methods.
The following shows the comparison result between soldier piles, which are generally used as steel material for temporary retaining walls in Southeast Asia, and Hat-type and H-shape combined high stiffness steel sheet piles.
Hat-type and H-shape combined high stiffness steel sheet piles can be easily fabricated on construction site or at a nearby yard or shop.We have prepared manuals for fabrication and can provide on-site instruction.

However, poIIution in one form or another has continued for many years, making it necessary for many countries to introduce IegisIation to protect the sea. Japan is no exception, and restrictions with regard to marine construction work and waste disposal have been tightened. For these reasons, Nippon SteeI Corporation has developed a non-polluting,high-speed prefabricated sheet pile ceIl method ( the Prefab CelI Method ),which incorporates all the advantages and none of the disadvantages of the conventional sheet pile cell method. With the new Prefab Cell Method, straight-web sheet piles are fixed in cellular form at an assembly site set up in caIm waters or on a speciaI barge near the installation site. The celI is then transported to the site and driven into the sea bed by a number of vibro-hammers operating simultaneously.
The Prefabricated Sheet Pile Cell Methodan Innovative, High-speed Marine Construction Method that Ensures Freedom from Sea Water Pollution.

Close-proximity installationNS-SP-J piles can be installed in close proximity to existing structures, permitting the construction of retaining walls abutting site boundaries and making maximum use of the site area.
100% intelock integrityAs interlocks are located on the outermost side of the wall, there is no need to consider the reduction of sectional properties due to slip on interlocks, and this permits economical design. Cost-saving and Work-shortening ofTemporary Work
Cost-saving and the shortening of temporary work timeCompared to conventional steel sheet piles for temporary work with an effective width of 400 mm, NS-SP-J has an effective width of 600 mm. This makes it possible to reduce the number of installed piles, with less cost and improved water tightness.

Corner-section sheet piles are a newly developed type produced by rolling, to replace the conventional T-shape corner-sheet piles produced by welding. Thus, these eliminate the need for welding and other fabrication processes and are far lighter in weight.
For assembly, the conventional cast equipment can be used as-is.
In particular, Larssen sheet piling has been adopted as a base for the shape of corner joints, in order to prevent detachment, and therefore, particularly, joint performance such as tment and repetition endurance is excellent.

Corner section: Hot-extruded shape steel
One of the methods for connecting a corner is the method of using hot-extruded shape steel, which is a product formed using a hot-extrusion method and not necessarily involving welding at the site. As shown in the gures below, this product is applicable for use at various angles.
V20JP is produced in Japan by Nippon steel & Sumitomo Metal Coporation under authority of PilePro LLC USA
To support a part of the external force applied to the steel sheet pile, sheet pile walls are often provided with waling, tie rods, and tie wires at the upper part of the steel sheet pile. The following gures show an installation example of a tie rod and waling.

Corner section: Irregular-shape steel sheet piles
Irregular-shape steel sheet piles are used for the change of the driving normal line of a steel sheet pile, for the correction of the intersection point of steel sheet pile walls, or for the correction of the slope of the normal line of a steel sheet pile wall. Irregular-shape steel sheet piles are manufactured by vertically cutting the web, assembling them in the intended shape, and welding them.

Angle-correction steel sheet piles
An angle-correction sheet pile corrects the angle when driving the sheet pile. This type of sheet pile is produced by either of the following two construction methods: a method that obliquely cuts two steel sheet pile webs to be assembled; and a method that cuts the center of the steel sheet pile web and assembles it by inserting a trapezoidal steel plate into the center. When using a trapezoidal steel plate, it is necessary to use steel with a strength equivalent to or stronger than that of the steel sheet pile base material.

Driving of a U-type sheet pileExecution details: Guide frames
Exection details : Concrete coping
In installation of steel sheet piles, it is necessary to install guide frames to ensure correct driving position and the stability of the steel sheet piles during construction. Here, one example is shown in which two rows of guide frames parallel to the normal line are driven at intervals of 2 to 4 m and in which the guide beam is mounted inside.
To prevent water from entering the joint or to improve joint efciency of U-type steel sheet pile, it is usually install the concrete coping at the top of steel sheet pile walls. Here, one example shown in below.

Sheet piles are pressed-in using hydraulic mechanism by grasping the middle place of sheet pile while taking reaction by holding driven piles. Driving machine is compact, and need no crane, though it needs crane separately for hanging sheet piles. It is applicable to the driving conditions such as narrow places and low clearance places. It is also possible to drive piles in conditions of low noise and low vibration. When ground is so hard that driving is difcult by using only pressing machine, it is useful to use water jet cutter together.

Example of construction using a hydraulic hammer
Percussion methodA percussion method is a method in which steel sheet piles are driven into the ground with the percussion force of a hydraulic hammer or diesel hammer. To prevent buckling at the head of the sheet pile, a pile cap is generally attached to the head of the sheet pile. Sheet piles cam be easily driven with high percussion force at a location with large joint resistance or ground resistance.

When steel sheet piles are used, multiple sheet piles are sometimes joined to obtain a specied length.In general, a weld joint is used.
When welding, it's need to choice welding rod as considering base material, thickness of sheet pile, position of weld. Here, shows the examples of welding material of JIS.
A steel sheet pile consists of continuous steel material and is itself water-impermeable material. However, considering the ease of driving, a slight gap is provided at the joint.It is known that, generally, the amount of water leaking from the joint is reduced over time by clogging sand.However, if you would like to stop water at an early stage, it is necessary to take measures to stop water at the joint.The most popular method is when swelling water-stop material is preliminary applied to the joint. Various water-stop materials have been developed for this. For details, please contact us.
The following methods are available to prevent the corrosion of steel sheet piles.(1) Designing the sheet pile considering corrosion allowance(2) Cladding using concrete to prevent corrosion(3) Coating the sheet pile to prevent corrosion
Four types are available with regard to this method: by painting; using organic lining: using petrolatum lining; or using inorganic lining.
(4) Electrolytic protection methodTwo types are available with regard to this method: by externally supplying a protection power source to prevent corrosion (external power method) or by attaching alloy such as aluminum and magnesium to the steel material as a sacricial anode (galvanic anode method).It is necessary to select the most-optimum corrosion prevention method according to the design and site condition. For details, please contact us.
